To all whom it Tri/dy ABEL T. ATH-Enron, a

Be it known that we,

A'rriEa'ro'N, dence, in the county of Providence, State of Rhode island, citizens oi theUnited States, have invented certain new and useful Tmprovements in Machines Jfor Spinning and Twisting Fibrons Materials, of lwhich the following is a specification. h

Our invention relates to that form ofspinning and twisting machines inwhich the spin@ ningand twisting are eliected through the intervention ci a rotating ring which 'carries an appropriate thread carrier or carriers and cooperates with whatis known in the art as' a upon the same or upon a bobbin carried by the objects of the invention being to provide means whereby these rotating rings, 1n ad 1 rendered capable" f .vertical and lateral adjustment, may at the same have their rotation rlciently and convenientlyy arrested when desired-than has been possible with the rings of'this .character as heretofore employed.

Tn all the figures like .letters oi` referencc are employed to designate corresponding parts.

A indicates the rings, and B the rail in which which we have shown two in the drawings, are are or may be provided with suitable yarn or thread guides and .areseverally constructed eeves A', with lrmed circumferentially around them-for reception ot a'band by means of which thering may be rotated'.` from the ordinary driving-drum or other source of power. f (Not shown.) In `some instances we form these threadguides `as slots a', which extend downwardly from the upper edges of their respective rings in an inclined direction and severally terminate at. their lowerends in orifices a2. At other times we find V1t dethey are or may be supported. These rings, of

threadfguides may be employed equal eliiciency. When, however., form of thread-guide a is employed it advantageous to employ two of `them on each ring. and to locate thern on opposite sides oi the axis thereohasthereby the employ ment of one is counter-balanced by the presence oi the other. The rail B,lon the other hand, is preferably constructed oi' the neces- `the hook sary length to suit it to the required number of rings that are to be employed, whether a single ring or a plurality of rings are-made we find use of, and is provided with a channel B in its upper surface, which extends from one end wall thereof to the other and is or may be divided up partitions 7), extending across wall toits rear wall xeither between the adjoining individual rings or between adjoining groups of rings, as may be preferred. Tith the rail provided with the partitions and walls L 2, as th it B3 connection with each ring. In the form of the invention which we have selected for purposes l four of these rolls.

of illustration we have shown as desired; number these rolls are preferably disposed around the rings at proper distances apart and are mounted in brackets D, of which there is a separate bracket for each roll. In'the construction of these brackets be adopted. We prefer, however, to construct them in bell-crank form, with one arm CZ of each provided with a groove or recess fZ, formed in and extending across its free end for reception of the friction-roll C, which is arranged therein. As thus constructed these brackets are severally secured' at the proper points in the'channel B of the rail B by appropriate screws (Z2 and (Z3, of which the former pass downwardly through the angular portions of their respective brackets and engage at their lower ends with threaded orilices in the rail, while the latter, d3, pass downMlv ward through suitable orifices (F, formed in lthe arms di of theirapp'ropriate belhcrank levers andsimilarl with like threaded orifices therein. The bracky engage at their lower end ets being thus secured in the channel of the rail B, the adjustment of their respective rolls C toward and away from dle may be effected by loosening the two screws (fand (Z3 and rotating the respective screws Z2 as pivots, after which the seeurcment of the rackets in place may be accomplished by tightening up both of these screws again by a screw-driver or otherwise,

various forms may the axis of the spin-A brackets upon theirl low of this rotary movement being imparted to the brackets the orifices d4, formed in the arms d" of the respective brackets D, are made somewhat larger in diameter than that of the screws d3, as shown in, Fig. 3. The brackets D being thus adjustably secured in the channel of the rail B, the rolls C are rotatively mounted therein through the intervention of suitable axes or studs c, to which I and in order to al suitable bear.- i are respectively mounted andy through ings c and 02,'wh1cl in the brackets above and below the pulleys,

as shown in Fig. 4. These bearings may be constructed in various formsand may be supported in various ways. le prefer, however, to construct them in the form of threaded sleeves with screw-driver-receiving nicks or slots in their upper ends and to support them 1n their respective brackets above and below the pulleys by threading'them in suitable orifices formed in such brackets, whereby they may be made vertically adjustable therein.

As thus constructed and mounted the adjustbrackets, severally contact at Vtheir inner ends with the peripheries of the bearings with which they respectively cooperate. While the rings A are thus supported by their respective friction-rolls C,

the contacting surfaces between the rings and their supporting-rolls may be of various In the drawings, however, we have shown them as formed of projecting V-shaped tracks a5 and cooperating V-sh Of these the Atracks (t5 are preferably form ed on the edges of circumferential flanges a6, which are constructedaround the downwardly-extending sleeves A of the rings A, while the cooperating'j grooves c3 are formed in the peripheri'es `of the friction-rolls C circumferentially of the same. With the con tacting surfaces between the rings and rolls aped grooves constructed as thus described the rings, while supported in' proper positions and capable of 'easy rota-tions thereon, are strained from any substantial vertical or an v'guiar motion with respect to the rail and may partake of any adjustments laterally or vertically that may be imparted to the rollsC. The form `of the contacting surfaces th us described, however, while etcient in operation, is merely illustrative, 'and the grooves, -as is obvious, may be made circular, rectangular, inclined, .or of other appropriate y contour in cross-section, and the relationship i of parts reverse with the rentrant surfaces positively re tracks and cooperating in the flange a of a depending sleeve A and the projecting cooperating surfaces formed tire length of the rail or may be :made up of sections that are independently "secured in place. Withfthe parts constructed as above described are employed .means by which the rotation of the rings may be arrested when `it is desired to mend or piece up broken ends. These means may be of various forms and may be located'in different relations with respect tothe rings. We prefer, however, to employ two levers E for. this purpose,which, pivoted at their inner to the under side of the plate BL', extend forward to near the front edge of the rail an curving around the ring are provided at their front ends with thumb-pieces e', which extend upwardly throughjsuitable slots b5 tothe upper side thereof, whereby to be readily grasped by the hand of the operator. As thus arranged 'the rotation ofthe ring may be arrested when 3 5 in operation by bringing the forward ends of the lever together, when the stopping of the ring will be effected by the friction occasioned, between its periphery and the interior of the levers. In some instances these levers E may be employed-without any additional frictionalV devices applied to their We prefer, however, to employ friction-pads e2, which may be made of leather or other appropriatematerial and are secured to the inner;

sides of the levers, as shown. While thus the rotation of the rings is arrested by bringing the levers against their peripheries, these levers when the rings are in rotation will be normally held out of contact therewith. 1Eer holding these levers in these inoperative positions various means have shown this result accomplished, however, by a spiral spring e", which is interposed between the forward ends of the levers and is 5t connected at its opposite endsto the-oppositely-arranged levers;

trative, and other equivalent means may be employed therefor if preferred.

With the lparts constructed as above described tlie eflicient mounting of the rings upon the supporting-rail is effected, and'not only are the rings made capable of vertical adjustment, as well as their cooperating rolls,

but this is only illusl on the rings, but in consequence of each of the supporting.friction-rolls being mounted in a separate bracket a more easy and accurate adjustment 'of' the rolls laterally to bring the rings into appropriate axial relationship with respect toV their coperating spindles in-` sured than is possible when two -or niore of these rolls are mounted in a single bracket. Moreover, b-ysecuring the brackets for the the bottom of the channel-way B in the rails B instead of to the -cover thereof greater firmness and stability of these .parts is insured,rwith the consequent result of a freer and more accurate operation of them. The rings and their supporting adjuncts being thus supported upon the rail B,

this rail may in turn be supported upon suitable guide-rods, whereby to have a vertical traverse to cause the rings to properly lay the yarns upon their respective bobbins, or the same may be fixedly secured in place and the spindles, with their appropriate bobbins,

It will thus be seen from the foregoing that we provide means for mounting the rings upon their supporting-rails and for arresting their rotation when required, which, while simple in construction and efficient in operation, permits of the adjustment of the rings both verlaterally when required to bring .Although in the above we have described the best means contemplated by us for carrying our invention into practice, we w1sh"it distinctly understood that we do not limit ourselves strictly thereto, as it is obvious that we may modify the same in various ways without departing from the spirit thereof. p .l Having now described our invention and specified certain of the ways in which it is or may be carried into effect, we
